Calculate the energy needed to produce 10 moles of Cl2O7 using this balanced equation.
2Cl +70+ 100kCal==2ClO7
if I needed to calculate for 7 moles, how would it change?

1. I think you have made one or more typos in your equation. I will assume the equation should be
2Cl + 7 O + 100 kcal => Cl2O7

If it takes 100 kcal for 1 mol then it will take 100 x 10/1 = ? kcal.
What would it take for 7. Can you handle that?
